Hi
Thanks for trying to help.
I did not see anything on that page you mentioned that i think is relevant.

I just tried on ubuntu 16.04 64bit in a virtual machine, there it compiles fine, just like on ubuntu 14.04 64bit.
So my guess now is that it is somehow related to that 32bit machine.

Well, what details can i give? It's a simple .pro file with some .c and some .h
On 64bit machines qmake/make produce an executable, on a 32bit machine it does not.
Qt Code: 
  1. TEMPLATE = app
  2. TARGET = 
  3. DEPENDPATH += .
  4. INCLUDEPATH += .
  5. QT       -= gui
  6.  
  7. # Input
  8. HEADERS += swedate.h \
  9.            swedll.h \
